Hello James, I have only checked oil pressure when vehicle is warm. I will check oil pressure tomorrow from cold and post back to you my results. but I am going to take yours and Alan's advices and check the big end and main bearings tomorrow as well. Spoke to customer today and he has all so told me that before he brought the vehicle in it did run out of oil and he topped it up. Anyway I will get back to you as soon as I can tomorrow and thanks again
